This is confirmed to be an acceptance, right? I just got "decision made" with amounts showing up for the seat deposits too.

I haven't heard of any cases in which it doesn't mean an acceptance (this, of course by no means means that it's a guaranteed acceptance) and it would seem odd to list a seat deposit amount when the applicant has no need to pay that amount. I know my logic is by no means tight, but from what I've gathered it means an acceptance.
